Featured Chinese Incised Enamel Bowl or Cloissonne?

Am having a hard time finding a name for these bowls that I have, they are not cloisonne as they don't have cloissonne wire, but yet the colors are seperated, also the bowls seem to be worked on from the inside out on the bronze the enamel is on. They measure 2-3/8"H x 4-1/2"W x 2-7/16" foot with measurements differentiating between both bowls. How old could they be? as, to me, they look old. Any help pointing me in the right direction would be greatly appreciated, thanks.

 

They are very beautiful.
The technique is simply called enamel. The metal is copper, not bronze. The style is Canton (Guandong).
I would call them antique Canton enamel blossom shaped bowls.

 

Any idea as to how lod they could be?

 

"old they would be"

 

Very nice bowls.

 

Sorry, I find these difficult to date, but they are antique, so at least 100yrs.

 

Very nice.

 

Hit the nail on the head, cool. Cantonese enamel it is, actually found an identical one listed as qa Ling?, anyway, thanks.
